Curated workout library with physiological targets
Import your own workouts from any source
Detailed Power Profile: Strengths, Weaknesses & FTP Estimate
Ride Screen: Precise Smart Trainer Control (ERG Mode)
Smart-Smoothing: Balances erratic power data for smooth trainer control.

Control from the bars.
Hands stay where they are.
Virtual Shifting puts your effort on the handlebar: with a Zwift Click you change your ERG target in structured workouts and trainer resistance in SIM mode — no reaching for the phone mid-interval. It pairs over Bluetooth like any other sensor. Verified with Click v1.
- ERG target from the bars: Nudge your target watts up or down without touching the phone.
- Resistance in SIM mode: Click resistance up and down while you ride, no stopping.
- Not a simulated cassette: The buttons act on resistance directly — same feel as shifting, no gear ratios modelled.
- Click v1 verified: That is the hardware we have tested. A v2 is untested, so we do not claim it.
Lactate, logged from your bike.
LT1 & LT2 estimated automatically.
ENDURE is the first cycling app that lets you log lactate readings during a ride, or add them afterwards. From those values it estimates your LT1 and LT2 thresholds automatically, with a confidence tunnel around the fitted curve. Your lactate data sits right next to your power data, so you don't need spreadsheets or a separate tool.
Logging a lactate reading for a workout.
What you get:
Lactate profile + LT1/LT2 with confidence tunnel.
Heat is a metric.
CORE body temperature & heat zones, live in your ride.
ENDURE is the first indoor cycling app to natively integrate the CORE body temperature sensor, with a live heat-zone display right on the ride screen. Pair it over Bluetooth like any other sensor. Your core temperature is recorded next to power and heart rate, ready for heat-training analysis after the ride.
- Native sensor pairing: Connect your CORE sensor over Bluetooth like a power meter, without running a second app.
- Live heat zones: See your current heat zone during the ride and pace your heat sessions accordingly.
- Logged with your ride: Core temperature is stored alongside power and heart rate for post-ride analysis.
How well do you actually climb?
Climbing Efficiency puts a number on it.
Climbing Efficiency scores how effectively you turn watts into vertical meters. ENDURE detects the climbs in your outdoor rides automatically and calculates a personal climbing score from them. It is one of the first apps worldwide to do this.
- Automatic climb detection: ENDURE identifies every climb in your outdoor rides.
- VAM-based scoring: The score is built on your vertical ascent speed in meters per hour.

Frequently Asked Questions
Everything you need to know before your first ride.
Is ENDURE free?
Yes, right now ENDURE is free on iOS and Android while we keep improving it. An affordable subscription is planned, so this is a good time to jump in.
Which smart trainers and sensors work with ENDURE?
ENDURE connects over Bluetooth to smart trainers, power meters and heart-rate monitors. If your trainer supports standard Bluetooth resistance control, ENDURE can steer it automatically in ERG mode.
Does ENDURE work with any turbo trainer?
For automatic resistance control, ENDURE needs a smart trainer that supports the Bluetooth standard FTMS — that covers the large majority of current models across all the well-known brands. A classic turbo trainer without electronic control cannot be steered, but you can still record the ride and all your analytics if you pair a power meter or heart-rate sensor.
Does ENDURE support Virtual Shifting?
Yes, with a Zwift Click — but it is worth knowing what it does. The buttons change your ERG target inside a structured workout and trainer resistance in SIM mode; ENDURE does not simulate a cassette the way Zwift does with its Cog, so there is no gear number. The feel is the same, the mechanism is resistance. Verified with Click v1.
Does my Zwift Click work with ENDURE?
A Click v1 does — that is the generation we have verified, on iOS and Android. It pairs over Bluetooth and changes your ERG target in workouts or trainer resistance in SIM mode. We have not tested a v2 yet, so we cannot promise it.
Which platforms is ENDURE available on?
ENDURE is available on iOS and Android. Desktop versions for Windows and macOS are planned, so you will be able to train on the big screen later too.
How does ENDURE estimate FTP and VO2max?
ENDURE analyses your recorded power and heart-rate data across rides to model your FTP and VO2max trends over time. You see your fitness evolve week by week instead of relying on a single all-out test.
What is the lactate (LT1 / LT2) feature?
ENDURE is the first cycling app that lets you log lactate readings during or after a ride. From those values it fits a curve and automatically estimates your LT1 and LT2 thresholds, with a confidence tunnel around the result.
Does ENDURE support the CORE body temperature sensor?
Yes. ENDURE is the first indoor cycling app with native CORE body temperature sensor integration. Pair it over Bluetooth and you get live core temperature and heat zones on the ride screen, recorded alongside power and heart rate.
What are heat zones and why do they matter?
Heat zones translate your core body temperature into training ranges, just like power or heart-rate zones. Spending controlled time in the right zone triggers heat adaptations such as higher plasma volume and better cooling, which pay off in hot races and support aerobic performance.
Is ENDURE a good alternative to Zwift?
It depends on what you want. Zwift is built around virtual worlds and racing; ENDURE focuses on precise structured training and analysis: FTP and VO2max trends, lactate thresholds, CORE heat zones. Many riders use ENDURE for training and analysis alongside or instead of Zwift.
How does ENDURE compare to TrainerRoad?
TrainerRoad centres on algorithm-generated training plans behind a subscription. ENDURE offers a curated workout library plus deeper physiological analysis: lactate LT1/LT2, CORE body temperature with heat zones and climbing efficiency.
Does ENDURE sync with Strava or intervals.icu?
Yes. ENDURE auto-uploads your rides to Strava and intervals.icu, and can sync your ride history from either on first launch, combining indoor and outdoor activities into one complete performance picture.
